There is loads of data available for this calibre
World competition F-Class shooters neck it up to 7mm - known as the 7-6.5 Alex wheeler


ADG 7-6.5 PRCW (Precision Rifle Cartridge) brass was designed in collaboration with Alex Wheeler specifically to create a 7mm round using ADG’s proven 6.5 PRC cartridge case specifically for ELR shooting.  This cartridge is literally our 6.5 PRC cartridge case only sized to 7mm.  As such, the neck thickness will be slightly thinner than the original 6.5 PRC cartridge or any fire-formed brass that you may have.  Our average neck thickness for the 7-6.5 PRCW cartridge is 0.0135″ as compared to 0.0149″ for our 6.5 PRC cartridge.  The average loaded neck diameter of 7-65 PRCW is 0.3120″.  Chamber reamers are available from JGS Precision in both a neck turn and NO neck turn variant.  You can order these directly from JGS with the following part numbers:

JGS Chamber Reamer Part Numbers:      NO Neck Turn – 7-65PRCW_NT    /    Neck Turn – 7-65PRCW

Regarding COL. If loading close to the lands then a reduced load would be needed as a pressure spike occurs due to the difficulty in starting the bullet. If hunting is the main application then 100% feeding and fit into the chamber is a given. I have always started with a COL of 1mm off the lands for cup and core and 2mm off for mono bullets. It has stood me in good stead and with charge adjustments have obtained MOA or better for all my hunting loads.]]> Reloading Methodology Tripodmvr https://systemz.online/reloading-methodology/6-5-prc#post-5444 Re: 6.5 PRC https://systemz.online/reloading-methodology/6-5-prc#post-5443 Mon, 30 Sep 2024 02:55:05 +0000
I've found that Vihtavuori is most generally available everywhere. The consistency of N570 through N555 is good enough that I don't need to change the load between batches.

It is a bit more expensive, but you save on not having to redo load development when the batch number changes.

I'd suggest picking a powder to burn 100% in the given barrel length. Retumbo, for example, in a shorter barrel is going to give incomplete burn, which reduces performance.

The powder you choose should ideally give close to 100% case fill.

GRT is a good start to picking a powder that gives 100% burn, and as close to 100% case fill as possible.]]> Reloading Methodology 414gates https://systemz.online/reloading-methodology/6-5-prc#post-5443 Re: 6.5 PRC https://systemz.online/reloading-methodology/6-5-prc#post-5442 Sun, 29 Sep 2024 23:03:45 +0000 Reloading Methodology troglodyte https://systemz.online/reloading-methodology/6-5-prc#post-5442 Re: 6.5 PRC https://systemz.online/reloading-methodology/6-5-prc#post-5441 Sun, 29 Sep 2024 21:53:05 +0000
For instance, 155gr Berger Hybrid in .308 win shot 1/2 MOA at 3mm (0.120") jump. Much better than it did at 0.5mm.

The outlier is Berger VLD bullets. Apparently they can be quite jump sensitive.]]> Reloading Methodology janfred https://systemz.online/reloading-methodology/6-5-prc#post-5441 Re: 6.5 PRC https://systemz.online/reloading-methodology/6-5-prc#post-5440 Sun, 29 Sep 2024 08:56:06 +0000 Reloading Methodology Againstthegrains https://systemz.online/reloading-methodology/6-5-prc#post-5440 Re: 6.5 PRC https://systemz.online/reloading-methodology/6-5-prc#post-5433 Wed, 25 Sep 2024 12:57:46 +0000
